Elaboration of the numerical rock model: conceptualization and geometric setup. a Thin section of the dolerite from RN-15/IDDP-2 (courtesy of HS Orka). b Conceptualisation: each crystal grain is modeled by a numerical particle; contacts between grains are modeled by parallel bonds (PB). c Schematic view of a detail of the numerical rock model: bonded particles aggregate (Py pyroxene, Plagio plagioclases, TiMg titanomagnetite). d View of the particles of the numerical dolerite model
